Camel Camelling.
Camel stops!
Jump off, hump off- look inside.
Rounds in the camel, no rounds in the hump etcetera, etcetera.
One they really beat into me was the four principles of marksmanship.
the position and hold must be firm enough to support the weapon
the weapon must point naturally at the target
the sight alignment must be correct
the shot must be released, and followed through without disturbing the aim
